FRAZIER, OFDETROIT, MICHIGAN, ASSIGNORS PRODUCTS COMPANY, OF DETROIT, MICHIGAN, ACORPORATION WALL GROUND WORK STRIP Application filed January 13, 1930.Serial No. 420,576.

This invention relates generally to improvements in buildingconstruction and more particularly to the provision of means f rsecuring wall ground work such as wall board and the like in place.

One of the principal objects of this invention is to provide means ofthe above type in the form of a strip which, in addition to securing thewall ground work in place, also functions to. separate adjacent sectionsof the ground work forming the wall and further operates to interlockthe plastic material applied to the ground work with the strips to forma homogeneous mass.

A further advantageous feature of the j the wall ground work in angularrelation to each other to present invention resides in the provision ofan anchor strlpcapable of being readlly deformed for securlng thevarlous sectlons of form a corner assembly. Astillfurther object of thisinvention is to provide a strip of the above character which may bereadily formed by a stamping or rolling operation and, as a consequence,lends itself to economical manufacture and also one :which may beexpediently secured to its sup port irrespective of slight surfacevariations of the latter.

vWiththe foregoing'as well as other objects manner in which the in view,the invention resides in the novel construction ofv the strip and themanner in which it cooperates with the wall assembly to form ahomogeneous mass.

In'the drawings: Figure 1 is a fragmentary perspective view illustratingone application of our improved anchorstrip. f I 1 .Figure '2 is asectional view showing the strip is secured to the Stud, members. I

' Figure 3 is a cross-sectional view'through the strip showing the. wallground work in position. I

Figure 4 is a plan view of a strip of metal illustrating the manner inwhichthe strip is formed. v Figure 5 is a sectional view showing the application of the strip to aninner corner as- Figure 6 is a view similarto Figure 5 showing the application of the strip to an outer cornerassembly.

Referring now to the drawings, it will be i":

noted that there is illustrated in Figure 1 an anchor strip 10 having abody portion 11 substantially channel-shaped in cross-section with theleg portions 12 of the channel terminating in oppositely extending footflanges 13. The foot flanges 13 cooperate with the leg portions 12 toform a rabbeted recess upon opposite sides of the base 14 of the channelfor receiving the adjacent sections 15 and 16 ofthe wall ground work.The construction is such that the adjacent edges of the sections 15 and16 abut against the legs 12 of the channel and, as a consequence, tancecommensurate with the width of the base 14 of the channel The width ofthe leg portions 12 preferably corresponds to the width of the sections15 and 16 so that the outer surfaces thereof are substantially flushwith the outer surface of the base portion 14 and forms in effect acontinuation thereof.

In order to secure the sections 15 and 16 in place upon the strip, thebase portion 14 of the latter is provided with a series oflongitudinally spaced struck out tongues 17 and 18 adapted to projectalternatively in opposite directions over the adjacent edges of thesections 15 and 16. As will be apparent from Figure major portions ofthe tongues are arranged flush with the exterior surface of the base 14and the end portions thereof are bent upwardly as indicated by thereference charare spaced from each other a dis- '3 of the drawings, the

acter 18' to facilitate engagement of the forms with the stripaninterlocking connection; It will also be noted that the plastic materialis permitted to flow into the openings formed by striking out thetongues 17 and 18 so that these openings also serve to interlock theplastic material with the strip.

Thus from the foregoing it will be observed that'the strip, wall groundwork and plastic material are rigidly secured together to form ahomogeneous mass. The width of the slots are predetermined and aresubstantially equal to the width of the material therebetween and sinceit has been stated v above that the notches are substantially f-shapedit will be apparent that the notches 20 and slots 21, in addition topreforming the above described function, also provide means for breakingthe strips to the desired lengths.

portions of the legs of the channel from the foot flanges and bendingthe latter outward- 1y to form a slot of suflicient dimension to permitthe portions 24 of the studs to engage between the legs and flanges. Inpractice, it has been found'that the above construction is suflicient tomaintain the strips in assembled relation with the studs without the aidof any-securing means.

Referring now more in detail to Figure 4, it will be noted that thestrip 10 is de;

velopedfrom a single sheet of'metal by' first punching the openings 21therein and striking out the tongues 17 and 18 and then fashioning thestrip to the desiredcontour by a stamping or rolling operation to formthe finished strip. In thisconnection it is to be noted that infashioning the material to form the completed strip, portions of theopenings 21 extend-into the leg'portions 12 of the channel 11 formingthe openings 19 andz20. I V j In Figure 5 wehave illustrated a strip25especially designed for inner corner assemblies to secure the sections26 and 27 of the wall ground work in angular relation to each other. Asshown, the strip is provided with flanges 28 and 29 extending at anangleto each other: corresponding to the angular relationshipiof the sections26 and 27 and adapted to engage the inner angular surfaces 30 and 81,respectively, of the stud member e 32. The flanges 28 and 29 areconnected to- 'getherby means of a web 38 having portions El-cooperating with the flanges 28 and 29' to form rabbeted recessesforreceiving the'sections 26 and 27. The adjacent edges of the sectionsa-re'adapted toabut againstthe portions 34 of'the web. and are held inplace by means oftongues 35; struck'out from the cen .The transformationof the strip 10 to the strip 25 is clearly illustrated in Figure 5wherein the strip 10 is illustrated in dotted lines. 7

In Figure 6 we have shown a strip 37 especially designed for exteriorcorner construction. This strip comprises flanges 38 and 39 adaptcdtoengage the exteriorly angular surfaces 40 and '41, respectively, of thestud member 42- with the longitudinal'edges 43 of the flanges adjacenteach other. Extending outwardly at substantially right'angles totheflanges 38 and 39 are flanges44 and 45, respectively, which formabutments for the adjacent edges of theground work sections 46 and 47.The flanges 44 and-45 are connected together by means of a web 48 havingthe struck out tongues 49 adapted toextend over theadjacent edgeportions of the sections 46 and 47 to secure the same in place. In thisconnection it is to be noted that the formation of the web 48 issubstantially the same as the base of the channel 14 0f the strip 7 11in that it is provided with openings intermediate the tongues49 for thereception of the plastic material. The strip illustrated in Figure 7 ispreferably identical in construction tothe strip. 10,

hereinbefore set forth, with the exception that the foot flanges 18are'provided with extensions 50; The extensions are preferably flaredoutwardly from the outer edges of the foot'flanges, as illustrated inFigure 7, and

are adapted to engage a suitable support.

Thearrangement is such as to provide a spring base for'the strip sothatany variations in the surface of the support will be compensated forby the re'siliency'of the extensions. The above form of strip findsparticular utility for use with steel joists where'- in theflower memberoften times'varies in level. What we claim as our invention g 1.
